Description

Technical Field

[0001] The present application relates to the field of home appliance control technology, and in particular to a stove control method and device for preventing pot overflow, and a stove. Background Art

[0002] Slight boiling, slight boiling and boiling are all phenomena of liquid boiling. The temperature of slight boiling is usually lower than the boiling temperature. In the slight boiling state, the liquid temperature is continuously maintained at around 95 degrees, and the bubbles are generated slowly and small. When the water in the pot is at a slight boiling, overflow can be effectively avoided.

[0003] As people's safety awareness increases, kitchen gas problems are gradually being taken seriously. Kitchen gas leaks are usually caused by improper use of open flames, non-standard operations, equipment failures, etc. The most common cause is human error, such as leaving the kitchen unattended during cooking. Once the water in the pot boils too much, the water in the pot can easily overflow and extinguish the stove fire, causing gas leakage.

[0004] Existing stoves generally have manually controlled fire levels. When the user starts cooking noodles or making soup, they will use high heat and cover the pot. After the user leaves, the stove cannot automatically adjust the fire according to the temperature, which makes it easy for the soup to overflow onto the stove surface, not only dirtying the stove surface, but also easily extinguishing the stove fire due to the overflowing soup, causing gas leakage. Summary of the Invention

A temperature sensor disposed on the inside of a pot lid collects temperature, and boiling is determined based on the collected temperature change.

[0050] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0053] Figure 2 is a schematic block diagram of a stove control device for preventing pot overflow according to an exemplary embodiment of the present invention;

[0055] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0056] Existing stoves generally have manually controlled fire levels. When the user starts cooking noodles or making soup, the stove will use high heat and cover the pot. After the user leaves, the stove cannot automatically adjust the fire according to the temperature, which makes it easy for the soup to overflow onto the stove surface, not only dirtying the stove surface, but also easily extinguishing the stove fire due to the overflowing soup, causing gas leakage.

[0057] The present invention provides a stove control method, device, and stove for preventing pot overflow. A temperature sensor and a humidity sensor disposed on the inside of a pot lid respectively collect temperature and humidity data. The method detects boiling based on changes in the collected temperature and humidity data. Once boiling is confirmed, the stove power is adjusted to maintain a slight boiling point. This prevents the food from being steamed while the soup overflows, thereby preventing the stovetop from becoming dirty. Furthermore, the method effectively prevents gas leaks caused by soup overflow.

[0058] There is also the safety issue of pots burning dry in the slightly boiling state. To address the problem of pots burning dry, the temperature collected by the temperature sensor is used to determine the pot's dry-burning state, control the main valve of the stove gas circuit to close, and send an alarm to the user so that the user can take emergency measures in time, thereby effectively avoiding kitchen fires.

[0059] The method of this application is described below through specific examples.

[0060] See also Figure 1 , Figure 1 is a flow chart of a stove control method for preventing pot overflow according to an exemplary embodiment of the present invention. Figure 1 , the method is applied to a cooker controller, the method comprising:

[0061] Step S11, receiving a first temperature value and storing the first temperature value in an array of a first preset length to obtain a first temperature array; the first temperature value is a temperature collected once every first preset time by a temperature sensor disposed on the inner side of the pot lid;

[0062] Step S12: When the first temperature array is full, the first temperature value received the most recently replaced the first temperature value stored the longest time ago as the latest temperature value;

[0063] Step S13: determining that the liquid in the pot has reached a boiling point based on the first temperature array and the latest temperature value; stopping replacing the first temperature value in the first temperature array to obtain a target temperature array;

[0064] Step S14: performing a corresponding adjustment operation on the firepower of the cooker according to the first temperature value last stored in the target temperature array and the first temperature value received in real time, so as to maintain a slight boiling of the liquid in the pot.

[0065] It should be noted that the stove control method for preventing pot overflow provided in this embodiment is applicable in specific practice to scenarios including but not limited to: gas stoves, electric stoves and other stove control application scenarios that require pot overflow prevention.

[0066] It can be understood that the stove control method for preventing pot overflow provided in this embodiment collects temperature through a temperature sensor arranged on the inside of the pot cover, makes boiling judgment based on the collected temperature change, and adjusts the stove firepower in time after determining that the water in the pot is boiling, so that the water in the pot is in a slightly boiling state. While the food is being steamed normally, the soup will not overflow and will not dirty the stove surface, and gas leakage caused by soup overflow will be effectively avoided.

[0067] In specific practice, in step S11 "receive the first temperature value and store the first temperature value into an array of a first preset length to obtain a first temperature array; the first temperature value is collected once every first preset time by a temperature sensor arranged on the inside of the pot lid". The first preset time can be between 1-60 seconds, or can be set to any time length. The best time is when the first preset time length is set to 3 seconds; the first preset length can be set to any value, and the best time is when it is set to 10.

[0068] Specifically, the first temperature value can be sent to the stove controller by the temperature sensor via wired or wireless means; or a pot cover controller can be set on the pot cover, and the first temperature value is first collected by the temperature sensor and sent to the pot cover controller, and then sent to the stove controller by the pot cover controller via wired or wireless means.

[0069] It can be understood that the technical solution provided in this embodiment collects the internal temperature data of the pot through the temperature sensor on the pot cover, thereby providing data support for overflow prevention control.

[0070] In specific practice, in step S12 "When the first temperature array is full, the first temperature value stored the longest is replaced by the most recently received first temperature value as the latest temperature value", if the length of the first temperature array is set to 10, the first temperature array is a, and the latest 10 temperature values ​​are sampled in chronological order and stored in a[0], a[1]...a[9] respectively; when a temperature value t1 is sampled again, a[0]=t1, and a temperature value t2 is sampled again, a[1]=t2..., and each time the most recently received temperature value replaces the temperature value stored the longest.

[0071] In specific practice, step S13 "determining whether the liquid in the pot has reached the boiling point based on the first temperature array and the latest temperature value" includes: each time the first temperature value stored in the first temperature array for the longest time is replaced, averaging the first temperature values ​​in the first temperature array to obtain a temperature average; obtaining a maximum temperature value and a minimum temperature value from the first temperature array; if the temperature average is less than the sum of the latest temperature value and the first preset value, and the difference between the maximum temperature value and the minimum temperature value is less than the second preset value, and the latest temperature value is greater than or equal to the third preset value, then determining that the liquid in the pot has reached the boiling point; if the temperature average is less than the sum of the latest temperature value and the first preset value, and the difference between the maximum temperature value and the minimum temperature value is less than the second preset value, and the latest temperature value is less than the third preset value, then determining that the liquid in the pot has reached the boiling point through humidity.

[0072] It should be noted that determining that the liquid in the cookware reaches the boiling point specifically involves: First, determining that the temperature of the liquid in the cookware rises slowly or no longer rises, and then determining that the liquid reaches the boiling point through the target temperature array. For example, if the first temperature array is a and the first preset length is 10, then the first temperature values (in °C) in the first temperature array are a[0], a[1],..., a[9] in sequence; the sum value SUM[0]= a[0]+a[1]+...+a[9]. The first preset value can be set to any value, and it is optimal to set the first preset value to 0.2. The second preset value can be set to any value, and it is optimal to set the second preset value to 0.2. MAX[a] is the first temperature value of the highest temperature in the first temperature array, and MIN[a] is the first temperature value of the lowest temperature in the first temperature array; if SUM[0] / 10 < a[9] + 0.2 and MAX[a] - MIN[a] < 0.2, it is determined that the temperature of the liquid in the cookware rises slowly or no longer rises, and the first temperature array is no longer replaced as the target temperature array; otherwise, after each replacement of the first temperature array, the judgment of whether the temperature rises slowly or no longer rises is made again until the judgment of whether the temperature rises slowly or no longer rises is determined; after determining that the temperature of the liquid in the cookware rises slowly or no longer rises, the boiling point of the liquid is determined through the target temperature array. For example, for a[9] in the target temperature array, if the third preset value is set to 100, if a[9] >= 100, it is determined that the liquid in the cookware is boiling; if a[9] < 100, the boiling point of the liquid in the cookware is determined through the humidity.

[0073] In specific practice, determining that the liquid in the cookware reaches the boiling point through the humidity includes: receiving the humidity value and storing the humidity value in an array with a second preset length to obtain a humidity array; the humidity value is the humidity of the cookware collected by a humidity sensor set on the inner side of the pot lid every second preset time interval; when the humidity array is full, the latest received humidity value is used to replace the humidity value stored for the longest time as the latest humidity value; determining that the liquid in the cookware reaches the boiling point based on the humidity array.

[0074] It should be noted that determining that the liquid in the cookware reaches the boiling point based on the humidity array includes: after each replacement of the humidity value stored for the longest time in the humidity array, performing an average value processing on the humidity values in the humidity array to obtain a humidity average value; obtaining the maximum humidity value, the minimum humidity value and the latest humidity value from the humidity array; if the humidity average value is less than the sum of the latest humidity value and the fourth preset value, and the difference between the maximum humidity value and the minimum humidity value is less than the fifth preset value, it is determined that the liquid in the cookware reaches the boiling point.

[0075] Specifically, the second preset duration can be optimally set to 3 seconds. Determining that the liquid in the cookware reaches the boiling point through humidity is as follows: For example, if the humidity array is b and the second preset length is 10, then the humidity values (in %rh) in the humidity array are b[0], b[1],..., b[9] in sequence; the sum value SUMb[0] = b[0] + b[1] +... + b[9]. The fourth preset value can be set to any value, and it is optimal to set the fourth preset value to 0.2. The fifth preset value can be set to any value, and it is optimal to set the fifth preset value to 0.2. MAX[b] is the maximum humidity value in the humidity array, and MIN[b] is the minimum humidity value in the humidity array; if SUMb[0] / 10 < b[9] + 0.2 and MAX[b] - MIN[b] < 0.2, then the liquid in the cookware reaches the boiling point; otherwise, make the judgment again after each replacement operation of the humidity array until it is determined that the liquid in the cookware reaches the boiling point.

[0076] It can be understood that the technical solution provided in this embodiment takes into account the low boiling point in the plateau area and combines humidity to determine the boiling point, which can adapt to more scenarios.

[0077] In specific practice, step S14 "performing a corresponding adjustment operation on the cooking appliance firepower according to the first temperature value finally stored in the target temperature array and the first temperature value received in real time" includes: performing an adjustment operation every fourth preset duration; if the first temperature value received in real time is greater than or equal to the first temperature value finally stored in the target temperature array, the adjustment operation is to control the cooking appliance firepower to reduce the preset power; if the first temperature value received in real time is less than the difference between the first temperature value finally stored in the target temperature array minus the eighth preset value, the adjustment operation is to control the cooking appliance firepower to increase the preset power; otherwise, the adjustment operation is to control the cooking appliance firepower to remain unchanged.

[0078] It should be noted that performing a corresponding adjustment operation on the cooking appliance firepower according to the first temperature value finally stored in the target temperature array and the first temperature value received in real time, for example: the first temperature value finally stored in the target temperature array is T, and the first temperature value received in real time is T S , it is optimal to set the fourth preset duration to 10 seconds, and it can also be set to a value between 5 - 15 seconds or any value. The preset power is optimally 0.5kw, and it is optimal to set the eighth preset value to 2. Perform an adjustment operation every 10 seconds. If T S >= T, the adjustment operation is to adjust the current of the proportional valve in the gas path of the cooking appliance, and the adjustment operation is to reduce the cooking appliance firepower by 0.5kw; if T S <= T - 2, the adjustment operation is to adjust the current of the proportional valve in the gas path of the cooking appliance, and increase the cooking appliance firepower by 0.5kw; if T > T S > T - 2, the adjustment operation is to control the cooking appliance firepower to remain unchanged.

[0079] In specific practice, this method further includes: receiving a second temperature value and storing the second temperature value into an array with a third preset length to obtain a second temperature array; the second temperature value is the temperature collected by a temperature sensor arranged on the inner side of the pot lid every third preset time interval; when the second temperature array is full, replacing the second temperature value with the longest storage time with the latest received second temperature value; determining that the cookware is in a dry-burning state based on the second temperature array; controlling the cooktop to stop heating and emitting an alarm so that the user can discover the dry-burning of the cookware and handle it in time.

[0080] It should be noted that determining that the cookware is in a dry-burning state based on the second temperature array includes: after each replacement of the first temperature value with the longest storage time in the second temperature array, performing a summation process on all the second temperature values in the second temperature array to obtain a total temperature value; when the total temperature values of a continuous preset number are increasing one by one over time, obtaining the most recently obtained total temperature value among the continuous preset number of total temperature values, and dividing the most recently obtained total temperature value by the third preset length to obtain an average second temperature value; if the sum of the average second temperature value and a sixth preset value is less than the latest received second temperature value, and the latest received second temperature value is greater than a seventh preset value, then it is determined that the cookware is in a dry-burning state.

[0081] Specifically, the second temperature value is collected by using the temperature sensor on the inner side of the pot lid. The temperature sensor can be the aforementioned temperature sensor or a separate temperature sensor specifically added to determine the dry-burning of the cookware. Then, it is determined that the cookware is in a dry-burning state through the second temperature array. For example, the third preset time interval is set to 1 second optimally, and the third preset time interval can also be set to any number of seconds according to requirements. The third preset length is 10, the sixth preset value is 10, the seventh preset value is 200, and the second temperature array is c. Then, the second temperature values (in °C) in the second temperature array are c[0], c[1], ……, c[9] in sequence; the sum value SUMc[0] = c[0] + c[1] + …… + c[9]. Every 1 second, after replacing the second temperature value with the longest storage time in the second temperature array with the received second temperature value, the sum value is calculated once, and the consecutive sum values SUMc[0], SUMc[1], ……, SUMc[9] are obtained in sequence. If SUMc[0] < SUMc[1] < …… < SUMc[9], it is determined that the temperature inside the cookware continues to rise, and the latest second temperature value T is detected. G If T G > SUMc[9] / 10 + 10 and T G > 200, then it is determined that the cookware is in a dry-burning state.

[0082] Specifically, when it is determined that the pot is in a dry-burning state, the stove is controlled to close the gas circuit of the gas stove or cut off the power of the induction cooker, and an alarm is issued to the user at the same time. The alarm can be one or more of the following: audio alarm, light alarm and information alarm; among them, the information alarm can be a message sent to the app or an alarm text message.

[0083] It can be understood that the technical solution provided in this embodiment is combined with a method for detecting dry-burning of pots and pans, which effectively avoids kitchen fires caused by dry-burning of pots and pans.

[0084] In specific practice, the temperature sensor and the humidity sensor are arranged at the top position of the inner side of the pot cover.

[0085] It should be noted that there can be one or more temperature sensors, which are set according to specific safety requirements and are installed at the top position of the inner side of the pot lid; there can be one or more humidity sensors, which are set according to specific safety requirements and are installed at the top position of the inner side of the pot lid.

[0086] It can be understood that the technical solution provided in this embodiment, which is set at the top position on the inner side of the pot cover, can more effectively collect temperature values ​​or humidity values.
